This is genuinely a super impressive project (especially because you guys said you started like a week before the end of the jam?!). There are so many technically impressive aspects of the game (procedural generation, the actual mining, etc.) and the core concept is genuinely really cool. The pixel art is also really well done, and the sprites look great. 

I do also have a couple small nitpicks with the game:

1. The UI controls are really weird when I go to isolate the malware to a different system. I wasn't able to actually click, and I had to move my right side to the arrow keys and then press space, all while holding tab so the UI didn't close. Personally, I would make it so you can click with the mouse and also have the tab key toggle the UI rather than having to hold it while I'm selecting my system.

2. The game was a little hard. Even when I specifically focused on routing to the syringes that slow down the malware, I still couldn't get past the second level. There are a couple things you could try to fix this, but what I would personally like to see is there be more caves, more syringes, and maybe have some of the higher tier blocks be a little easier to mine.

3. While the ground tiles themselves look really good, I think the aesthetic of the game would've seem more immersive if, when there were no tiles bordering it on a certain side, the sprite changed slightly to be more aligned with the rest of the world (the best example would be how Terraria rounds exposed corners of blocks). 

Obviously I talked a lot about the few things I think could be improved a bit, but they really are mostly nitpicky stuff, and with more content, I think this game has a lot of potential. Again, the core concept is really interesting, and made the gameplay incredibly engaging (having to think about multiple things at once rather than just mindlessly mining away), and the soundtrack and sfx were really well done too. Overall, really great entry!
